MOQUETTE CARPET.

SPECIFICATION forming part O' Letters Patent No. 432,763, dated July 22, 1890.

Application filed February 2'?, 1888. Serial No.` 265,363. (Specimens.)

To @ZZ whom it may concern:

Beit known that I, ROBERT F. PATTERSON, of Clinton, county of Worcester, State of Massachusetts,have invented an Improvement in Moquette Carpets, of which the following description, in connection with the accompanying drawings,is a specification, like letters on the drawings representing like parts.

This invention relates to that class of carpet known as Moquette,7 it being a carpet wherein rows -of tufts are confined in place by weft-threads.

My invention has for its object to improve that class of Moquette carpet where the weftthread employed is inserted double and is of the same size, there being but one weft, it serving not only to enter and lock with the warps to form the body of the fabric, but also to hold the tufts constituting` the face of the fabric.

In my experiments to improve Moquette carpets I have discovered that difculties and objections inherent in such carpets as previously made may be overcome by a change in the structure of the fabric. The fabric herein shown may be lmade on a loom such as described in United States Patent No. 330,069, dated November 10, 1885, with but a slight difference in the order of opening the sheds in the body-warps.

In accordance with myinvention the sheds in the body-warps remain open for the reception of three shots or crossings of filling inserted double, one of the three shots of iilling receiving the tufts about it, the 4other two shots being beaten into the shed, one close to and against the side of the tuft to aid in holding it in place, while the other is beaten below the bight of the tuft on the weft about which it is looped, keeping said tnft set up closely.

tufts; but, if desired, I may use a third harness for a stuffer-warp, so as to give a little more body to the carpet, such stuifenwarp being laid in straight.

Figure l in longitudinal section shows my improved fabric with the threads widely separated. Fig. 2 is a similar view of a modification with the stutter-warp omitted. Fig. 3 is a plan view showing some of the warps with the crossing-weft and omitting the stuerwarp; and Fig. t is a section showing the carpet, represented in Figs. 2 and 3, as beat up closer.

Y The warp-threads aand h are carried by two harness-frames and arranged in pairs, and they areso opened or shed as to remain open for three picks after each crossing of the warp to form a shed, each shed in the main warps a and b thus receiving three shots of weft or filling d d d2, as shown, the shot d receiving upon it the tufts e, while the shots d d2, when beat into the shed, occupy the position shown in Fig. at with relation to the shot of tilting d holding the tufts, the said shots aiding in binding the tufts e and forming a seat for the tufts on the shot CZ, setting up said tufts, as it were, thus holding the rows of tufts very firmly and very close together.

To strengthen the carpet and add body thereto I may incorporate with it a stofferwarp, as c, Fig. l, it separating the two shots d d2 and lying straight in the fabric.

By separating the warps to form sheds and by leaving the shed open for the reception of the three shots of filling inserted double before again crossing the shed, it is possible to make a heavierand stronger fabric than byany other inode of weaving known to me, and it is also possible to get the three shots ot' `filling beaten into the same shed, so that the shots which do not directly receive the tufts about them serve thoroughly to bind and'setup and compact the tufts closely together. The warpthreads are so moved that when one pair is up the other pair is down; but it is not material that all the pairs of threads a or of threads b should be up simultaneously.

I am aware that it has been attempted to provide a Moquette carpet with a continuous back, as in United States Patent No. 257,395; but in the fabric described in said patent the IOO tufts surrounding one weft, as d, are not held in place therein by the contact against the said tufts of a second weft Without the intervention of aWarp-threadY1 and as a result the roWs of tufts are not as much set up, nor are they7 as close together when beat up, nor are the individual tufts as closely held.

Vhat I claim is- The herein-described tufted carpet, cornposed of two sets of body Warp-threads ct and b, arranged and Worked in pairs, tW`o threads a a constituting a pair and two threads b b constituting a pair, and the threads of each pair appearing side by side at one and then at the other face of the carpet and falling on opposite sides of the longitudinal row of tufts common to such pair, and three shots of ll ing in each shed between the body Warpthreads, one shot, as d, receiving about it the tufts e, while another of the said three shots of filling, as cl2, cornes in direct contact with the said tufts on the shot d Without the intervention of a Warp between thern,the other shot d being beaten into position under the shot (l, about Which the said tufts are looped, to thus constitute a seat for the said tufts and set them up, substantially as described.

In testimonywhereof I have signed myname to this specification in the presence of two subscribing Witnesses. v a
